Are Viruses Living or Not???

The Virus

What is a virus?
Do you think it's living or nonliving?
Why?

The picture on the left just so happens to be a virus (which everyone is 7-1 should know by now). A virus is a small particle that needs a host cell to live in and reproduce. To answer the question if it is living or not. I would say no, I do not think it is living.

In our notes it said:

Not Considered Living
.a virus is not a bacteria, fungus, protist, plant or animal.
.they cannot carry out cellular functions
.A virus can not replicate without infecting cells and then using the organelles an enzymes of the cells of the host.

I think it is not living because WAY in the beginning of the year, we were talking about characteristics of living things.

Our notes then said:

Characteristics of Living Things
-Living things move, use energy, grow and develop, respond to a simulus, and reproduce.


Although a virus can reproduce and move, it still can not use energy, grow and develop, or resong to a simulus, or im pretty sure they dont. ?:(.

That is why I think that viruses are not living.
